CHARLES EDOUARD JEANNOTTE, OF MONTREAL, QUEBEC, CANADA. v

VATER-HEATER.

Application filed January 16, 1919.

To aZZ whom t may concern:

Be it known that I, CI-IARLEs EDOUARD JnnNNor'rE, residing at 99 Parc avenue, Montreal, Quebec, Canada, have invented certain new and useful Improvements in Water-Heaters; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to water heaters, and one of the primary objects of the invention is to provide an improved heater of the vertical water column type, which will be simple and compact of construction and especially cheap to manufacture.

The invention will be understood with the aid of the accompanying drawing which illustrates a longitudinal section through the heater.

The heater casing 1 is provided with a water inlet 2 and outlet 8, and 4 is a base plate rigidly secured to the iianged lower end of the casing 1 by the nuts 5. A packing 6 may be provided between said plate 4 and the flange on the casing. The plate 4 is provided with a central opening 7 preferably threaded, and 8 is an inner casing having at its top a plurality of holes 9. 10 is a base plate, here illustrated as threaded in the lower end of the inner casing 8, said plate being provided with a central depending tubular portion 11 which is threaded at its lower end and engages the central hole 7 in the bottom plate 4. 12 is a threaded central hole in said plate 10 communicating with the upper end of the tube 11., and 13 are a plurality of holes corresponding in number and in alinement with the holes 9 provided in the top portion of the casing 8.

Between said top portion of the casing 8 and the plate 10, there are arranged inside said casing a plurality of vertical tubes 14, which are threaded in the holes 13 provided in the bottom plate 10 and are expanded at their upper ends in the holes 9.

Intermediate of said casing 8 is provided a steam pipe 15 which is connected to a suitable steam supply. This pipe is threaded in the hole 12 and projects downward through the tube 11, but is preferably smaller in size than the said tube 11, thus providing an intermediate air space.

A spiral condensation pipe 28 is connected Specification of Letters Patent.

to the bottom of said casing 8 at one end and leads to the water supply pipe 21.

It will be readily understood from the e" foregoing that the steam supplied to the pipe 15 will flow through that pipe and escape at the upper end thereof, which terminates short of the top wall of the easing 8, into the interior of said casing, where it circulates around the Water tubes 14 and quickly heats the Water passing through them. During its passage around said tubes and through the casing 8, the steam naturally condenses and is discharged through the spiral pipe 23, after which it may, if desired, be re-heated.

Particular attention is called to the arrangement provided in the bottom of the casing 1 through which passes the steam pipe 15. As will be clearly seen from the drawing, an air space is provided between said pipe 15 and the downwardly projecting tube 11; and as a result, the cold water which enters at the bottom of the casing 1 will not chill the steam which passes through the pipe l5 and cause it to condense before entering the casing 8. This particular feature is considered of extreme importance.

A further important feature is the spiral condensation pipe 23. By providing a spiral pipe inside the casing 1 adjacent the water inlet, the condensation water will necessarily radiate heat which will warm up the cold water entering the inlet 2.

What I claim is:

1. A water heater comprising an outer casing having a water inlet and outlet, an inner casing within the outer casing, a plurality of vertical tubes within the inner casing and opening through the opposite ends thereof, means for supplying steam to the interior of said inner casing, means providing an air space between said steam supply means and said outer casing to prevent the cold water entering the outer casing from contacting with the steam supply means, and means drawing oil' the water of condensation from said inner casing; substantially as described.

2. A water heater comprising an outer casing having a water inlet and outlet, an inner casing within the outer casing, a plurality of tubes within the inner casing and opening` through the opposite ends thereo, to draw off the Water of condensation; sube steam supply pipe proj eating through seid stentially as described.
